It depends entirely on what your goals are on the low bands.
DX is primarily a low angle mode ... the low dipole may have more
gain at its maximum point but unless the dipole is more than 1/4
wave above ground the gain is entirely at angles suitable only for
NVIS purposes. Once the horizontal antenna gets above a half wave
above ground (the break even point is .4 wave) it's low angle (DX)
performance begins to overtake the vertical. Unfortunately, most
of us do not have the ability to put up 120' towers with yagis for
80 ... and 250' towers with yagis for 160 meters.
